Sri Lanka Scimitar-Babbler

Medium-sized, slim shrike patterned in dark gray, black, and white. The male has completely white underparts, while the female has a rufous flank patch. There are large white slashes across the shoulders. Found along forest edge and in forest clearings, lush woodland, cultivations, and gardens. Usually seen singly or in pairs. The song is a slow, highly varied series of many different types of notes, and can include imitations of other birds. Similar to Northern Fiscal, but has a gray crown and back. Distinguished from other black-masked, gray-backed shrikes by the lack of a white nick on the wing.

Dark ash-gray petrel of cold southern seas. Small- and stout-bodied overall, but with a large, “puffy”-looking head. Note underwing patterning, with a pale “shoulder” separated from pale-based primaries by a broad, diffuse dark bar. Flies quickly and strongly, often arcing up to impressive heights above the waves on angled, sharply kinked wings. Can be difficult to distinguish from other dark medium-sized petrels at a distance, but note pale patches under the wings, overall gray body coloration, relatively large “cute” head, and flight style. Often forages at night. Nests in loose colonies on the Prince Edward, Crozet, and Kerguelen Islands, as well as Gough Island.

Large arboreal spinetail restricted to the upper Cotacajes river valley in NW Bolivia, where primarily known from the Inquisivi area in open woodland near treeline. From the similar Ash-browed Spinetail by whitish breast and pale nape. Song a very high, accelerating series of about 20 squeaks given over ~1.5 seconds that drops slightly in pitch over the course of the song.
